Hi,
When trying to know if a graph exists on a local Virtuoso RDF graph, the return
is always "true", wether th, graph already exists or not.
I tried:
ASK{GRAPH {}}
and
ASK{GRAPH {?s ?p ?o}}
The empty graph is known for being source of problems. What should be the
query to do against a Virtuoso database?
Pest,
Jibé
